In a long jump, an athlete sweeps one of her arm clockwise through 0.5 revolution and the other arm sweeps counterclockwise through 1.0 revolution in 0.7s. Treat each arm as a thin rod of mass 3.0. kg and length 0.5m rotating around one end. In the athlete’s reference frame, calculate the magnitude of the total angular momentum of the arms around the common rotation axis through the shoulders. (given I thin rod = MR^2)
